2 Claims.

The present invention relates to new and useful improvements in angle gauges adapted for quickly determining the angle setting for cutting tools, milling machine vises, miter boxes, or laying out work with a proper angle.

An important object of the present invention is to provide a tool of this character of simple and practical construction, which is efficient and dependable, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which:

Figure 1 is a front elevational view.

Figure 2 is a side elevational view.

Figures 3 and 4 are sectional views taken respectively on the lines 33 and 4-4 of Figure 1.

Figure 5 is a fragmentary sectional view taken substantially on the line 55 of Figure 1.

Figure 6 is a front elevational view of the lower member of the gauge.

Figure 7 is an edge elevational view thereof.

Figure 8 is a front elevational view of the slide carried by said lower member.

Figure 9 is a front elevational view of the upper member of the gauge.

Figure 10 is a perspective view of the pivoted indicator.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the

numeral 5 designates the lower hand gripping member of the gauge which is constructed of relatively thin flat metal and includes a leg portion 6 having a laterally extending arm I at its upper end, the rear face of the arm being provided with a lug 5' having parallel upper and lower edges.

The arm I is also formed with a longitudinally extending slot 9 disposed at right angles to the leg 6 and the upper edge of the arm. at its outer end, is formed with a tapered lug I constituting an indicator.

The upper member of the gauge is designated at II and is likewise constructed of thin flat metal and includes a lower section I2 having a channel-shaped guide 8 on its lower edge slidably receiving the lug The upper member I I is also provided with an upwardly extending arcuate plate I3 connected at its upper edge to the bottom section l2 by a leg I4. A set screw I5 is carried by the bottom section I2 of the member H and projects through the slot 9 of the lower member 5 to secure the upper member II in transversely adjusted position.

The front face of the lower portion I2 of the upper member II is formed with graduations I6 with which the indicator I0 cooperates and the front surface of the arcuate plate I3 is also formed with graduations H.

A tubular slide I8 is slidably mounted on the leg 6 and is secured in vertically adjustable position thereon with graduations 20 with which an indicator 2| carried by the slide cooperates.

A tongue 22 projects from the upper edge of the slide I8 and is formed with an opening 23 for receiving a screw 24 freely movable in a slot 25 extending longitudinally in the lower end of an indicating finger 26, the finger being pivoted intermediate its ends on a screw 27 secured in an opening 28 adjacent the angle of the lower portion I2 and leg I4 of the upper member II. The upper end of the indicator 26 tapers to a. point which overlies the arcuate plate l3 for cooperation with the graduations l1 thereon.

The rear face of the upper portion of the indicator 26 is formed with a pin 26' engaged by one end of a spring 29 which has its other end secured on the screw 21 between washers 30-40 to retain the indicator under tension.

In the use of the gauge, by adjusting the slide I8 vertically on the leg 1 and adjusting the lower member 5 on the upper member II in accordance with the known measurements, the indicator 26 will then swing on its pivot 27 to indicate the correct angle.

It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further explanation.

Having described the invention, what is claimed as new is:

1. An angle gauge comprising a pair of slidably connected members each having graduations thereon arranged at right angles to each other, an indicator on one member movable therewith along the graduations of the other member, a slide on said one member having an indicator movable therewith along the graduations of said one member, said other member also having arcuately arranged graduations, and an indicator pivoted on said other member in and swingable over the arcuate graduations and connected to the slide for actuation of the pivoted indicator in accordance with the movement of the slide and in accordance with the movement of the members relative to each other.

2. An angle gauge comprising a pair of flat members, means slidably connecting the members at an edge portion thereof, graduations at the connected edge of one member, an indicator on the other member and movable therewith for registration with the graduations to indicate a predetermined sliding movement of the members, a pointer pivotally carried by said one member, an angle scale also carried by said one member over which the pointer is movable, said other 10
